Dotsure Car warranty(Gold) is a ****

Dotsure car warranty(Gold) is a **** and their service is very poor. My car had a mechanical breakdown as it was overheating and I took it to my nearest BMW dealership to be diagnosed. I was then provided with a damage report/quotation that highlights all issues on the car . Majority of the components on the damage reports provided by BMW are listed on the parts covered by Dotsure such as cylinder head gasket. Post submitting my claim I received a claim rejection letter via an email saying my claim is rejected as they don’t cover oil leaks repairs . My car is overheating and this has nothing to do with an Oil leak. They are so quick to sell you their product and assure you that you taking out a great car warranty plan, I would not recommend anyone to use their cover because you can only expect disappointment. I actually urge you to review my claim, send an assessor to BMW to verify what the main issue is as I don’t believe overheating is due to oil leakage.You can’t just reject a claim without even verifying information from BMW or sending an assessor. Please have this sorted out immediately.
